【摘要】 通过４９ｍ　× １００ｍ，４５ｍ×８１ｍ，６０ｍ×１１７ｍ三个双层柱面网壳在不同结构形态、各种支承条件及轻、重屋面荷重下的计算分析，对柱面网壳结构选型、计算假定等作了详尽的论述；并讨论了对于柱面网壳支座水平推力的处理、温度应力对大跨度柱面网壳的影响等不能回避的问题，指出网壳支座与平板网架支座节点的不同，提供了常见支承条件下网壳支座的设计思路和作法。更多还原

【Abstract】 Based on the design and research of three double-layer barrel vaults, authors give the structral style selection, the method of analysis and calculation plans. Also, static force characteristics of the barrel vault under different kinds of plans are analysed. Finally, the effects of temperature stress and horizontal support reaction are discussed.更多还原
